Specification of Letters Patent.

Patented July 23, 1907.

Application filed May 7, 1907- Serial No. 372,334.

To all whom it may concern:

Be it known that I, ROBERT B. HUMAN, a citizen of the United States, anda resident of Ohickasha, in District 19, Indian Territory, have inventeda new and useful Improvement in Stalk-Gutters, of which the following isa full, clear, and exact description.

The purpose of the invention is toprovide a revolving'stalk cutteradapted for use in cutting stalks of any description upon any characterof ground, and which is absolutely complete in itself but is soconstructed that it can be quickly and conveniently attached todifferent wheeled machines, for example, disk cultivators or diskharrows, particularly the form wherein there is no necessity forremoving any of the regular parts of the machine, but wherein the cuttermay be applied without disturbing any of the operating parts orinterfering with their functions, the cutter being also capable of beingalmost instantly removed, leaving both it and the machine in tact.

It is a further purpose of the invention to so construct and connect thestalk cutter to a disk cultivator, that while it will not assist thecultivator it is assisted by the cultivator in doing its individual workas a stalk Cutter. 1

The invention consists in the novel construction and combination of theseveral parts, as will be hereinafter fully set forth and pointed out inthe claims.

Reference is to be had to the accompanying drawings forming a part ofthis specification, in which similar characters of reference indicatecorresponding parts in all the figures.

Figure 1 is a rear elevation of a disk cultivator and a longitudinalsection through the applied cutter and a section through the cultivatordisks between which the cutter is located; Fig. 2 is a side elevation ofthe stalk cutter; and Fig. 3 is a transverse section through the same.

In the drawings I have illustrated the stalk cutter as applied to anordinary disk cultivator, wherein A represents the arched axle providedwith the customary supporting wheels 10, and above the axle a seat frame11 is located, extending to the spindles of the axle and on said framethe drivers seat 12 is located.

B represents the main frame of the cultivator, which is provided withrearwardly extending adjustable arms 13 provided each with a downwardlyextending fork 13, and in these forks shafts 14 are mounted to revolve,each shaft being provided with a series of cultivator disks 15 havingtheir outer faces convexed and their inner faces concaved, and one diskon each shaft is located outside of the end member of the forksupporting the shaft, and at the inner end of each of said shafts 14 apolygonal fastening device forthe disks 15 is located and designated as15. The mainframe B is operated to raise and lower the cultivator disksby means of the customary levers 16.

With reference to the stalk cutter D shown in detail in Figs. 2 and 3,this cutter consists of opposing heads 17 and 18 of spider-likeconstruction, and outer faces d of these heads are convexed to conformto the concaved inner faces of the cultivator disks 15. The arms 19produced on the heads 17 and 18 by the said spider- I like. constructionhave corresponding longitudinal edges inclined and their opposinglongitudinal edges straight, as is best shown in Fig. 3, and at thestraight longitudinal edge or face of each arm 19, an inwardly extendingbracket 20 is formed, being at right angles to the arm carrying it andblades 22 connect the heads 17 and 18, being secured to the brackets bybolts 21 or their equivalents, and the cutting edges 23 ofsaid bladesextend a desired distance beyond the outer ends of the arms of the headsand the construction of the cutter D is completed by the formation inits heads of centrally located polygonal openings 24 adapted to receivethe polygonal fastening devices 15 on the cultivator shafts 14 abovereferred to.

In making the application of the cutter to a disk cultivator, the forksl3 are adjusted outward so that the cutter D may be placed between theinner ends of the shafts 14 and then the said forks are adjustedinwardly until the polygonal fastening devices 15 enter the polygonalopenings 24 in the heads of the cutter, as is shown in Fig. 1, whereuponthe forks 13 are secured in position. Thus it will be observed that theattachment'may be readily made and without disturbing any portion of thecutter or any portion of the implement to which the attachment is made.

It will be observed that in the attachment of the stalk cutter to or thedetachment of the same from a disk cultivator no extra pieces or partsare used and none is required to be removed.

The device combines the features of light draft and a quick and easymethod of attaching and detaching; it has no intricate parts to wear orto be adjusted or particularly operated; it has no bearings of any kindto become worn and it will operate on uneven land, as the disks will cutthe limbs or branches and all stalks that lie close to the ground.

Having thus described my invention, I claim as new and desire to secureby Letters Patent,'

1. A stalk cutter comprising opposing heads having convexed outer faces,said heads being of spider-like construction, the arms formed therebyhaving brackets at corresponding longitudinal edges, and bladesconnecting the heads and secured to the brackets.

2. A stalk cutter comprising opposing heads of spiderlike formation,said heads having convexed outer faces, the arms of the heads havingcorrespondingly inclined and opposing straight longitudinal edges,brackets extending inward from the straight longitudinal-edges of 'thearms of fig may

said heads, the heads having each a polygonal opening there in, andblades connecting the heads and secured tosaid brackets.

3. The combination with opposingshafts 01f anagricnl- 5 tural implement,disks upon said shafts having concaved inner and convexcd outer facesand a polygonal fastening deviceat the inner end of each of the shafts,of a stalk cutter consisting of spider-like heads having convexed outerfaces to fit to the concaved inner face'of the inner 10 disks on saidshafts, and polygonal openings to receive
